aFe 51-76012 Momentum GT uses one three-layer oil-free synthetic Pro DRY S filter, black XLPE intake tube and sealed sight-window housing for the Tacoma 4.0L V6. The kit retains and relocates the original smog pump and transfers the original MAF and engine-cover mounting stud.
Toyota Tacoma 2012-2015 with the V6-4.0L gasoline engine. The exact current product page and shared manual agree. Exact-part retailer tables retain Base and Pre Runner 2012-2015, TRD Pro 2015 and X-Runner 2012-2013; no later X-Runner extension is inferred. The current manufacturer page explicitly states compatibility with models equipped with Magnuson or TRD superchargers, but actual installed configuration and connections must match. This does not approve a different engine or every aftermarket supercharger arrangement.

| Brand | aFe POWER |
| Manufacturer Part Number | 51-76012 |
| Application | Toyota Tacoma 2012-2015 V6-4.0L; exact supercharger configurations require matching |
| Filter / medium | 21-91123 / three-layer oil-free synthetic |
| Tube / housing | 05-76004B1 / 05-76004B2; black XLPE |
| Coupling / trim | 05-01470 bellows / 17-inch trim seal |
| Smog pump | Original unit retained; supplied 05-12332B4 bracket |
| Isolation mount | 03-50063; hand tighten rubber mount only |
| Hardware and dimensional qualification | One selected Pro DRY S filter is supplied, not all three media listed in the shared manual. Current exact pages describe a 9-inch filter; older exact-part retailer copy describes 8 inches. That dimensional/revision discrepancy remains qualified rather than treating one boxed height as visually measured. The shared manual uses 05-prefixed T-bolt and MAF-screw codes as printed; they are not silently replaced with similar 03-prefixed codes from another kit. No new MAF, new smog pump or complete replacement CCV hose is listed. The original smog pump and all its electrical/airline connections are retained and relocated, not deleted. |
| Flow qualification | The actual family chart shows 460 CFM for Pro DRY S versus stock 210 CFM at 7 inches H2O, about 119% higher. The other media bars are separate choices, not extra supplied filters. This is a bench-flow comparison, not a guaranteed power or filtration-efficiency improvement. |
| Dyno qualification | Both linked dyno charts are identical and label the tested run 54-76004 Final, a related Pro 5R configuration rather than a distinct dry or later-kit test. At the marked 4.1k-rpm point, 192.27 minus 182.44 hp is 9.83 hp and 246.30 minus 233.71 lb-ft is 12.59 lb-ft. Run maxima change from 203.11 to 217.01 hp and 242.77 to 252.30 lb-ft: 13.90 hp and 9.53 lb-ft peak-to-peak, at different peak rpm. Both notes specify third gear, manual transmission, traction control off and a blade fan. Baseline notes specify 295/75 tires and full stock; the intake notes do not repeat tire/exhaust configuration. SAE is 1.01 for both, temperatures and humidity differ, and RPM pickup changes from inductive baseline to OBD2 intake. Hood position and test vehicle year are not identified in the chart. Current 10 hp/13 lb-ft headlines are not independent guarantees for this exact dry/later/supercharged combination. |
| Recheck / torque | 100-200 miles / no numeric torque supplied |
| Emissions | The current exact manufacturer pages and manuals state that this product is not currently CARB exempt and is unavailable for purchase in California or use on a vehicle registered with the California DMV. A fitment statement for a supercharger does not establish emissions approval. |

Which filter medium and dimensions are established?One 21-91123 Pro DRY S three-layer oil-free synthetic filter. Current exact manufacturer pages say 9 inches high while older retailer descriptions say 8 inches; verify the boxed revision instead of assuming the two descriptions match. Clean, fully dry and do not oil dry media.
Is the original smog pump removed permanently?No. Transfer its three rubber insulators to bracket 05-12332B4, retain its original C-clips and reconnect its electrical harness and airline. Route the male harness connector UNDER the bracket and airline OVER the intake tube.
Which mounts and engine-cover hardware transfer?Transfer two original housing grommets and steel sleeves, plus the original engine-cover mounting stud using an E6 socket. Replace the A/C bracket screw with the supplied rubber isolation mount and HAND TIGHTEN ONLY. Reinstall the cover on its transferred stud and original nuts.
Which hoses and MAF parts are reused or supplied?Transfer the original MAF with the two printed 05-50491 screws. Replace the small vacuum line with the supplied 16-inch 5/32-inch hose, fit the brass nipple and reconnect the original CCV hose. No new MAF or replacement CCV hose is listed.
Does the housing require the optional scoop?No. The exact intake BOM includes an auxiliary-inlet urethane plug, while the scoop is a separately sold accessory with its own instructions and hardware. The plug is not a fording-depth certification.
What do the actual flow and dyno charts establish?The actual family chart shows 460 CFM for Pro DRY S versus stock 210 CFM at 7 inches H2O, about 119% higher. The other media bars are separate choices, not extra supplied filters. This is a bench-flow comparison, not a guaranteed power or filtration-efficiency improvement. Both linked dyno charts are identical and label the tested run 54-76004 Final, a related Pro 5R configuration rather than a distinct dry or later-kit test. At the marked 4.1k-rpm point, 192.27 minus 182.44 hp is 9.83 hp and 246.30 minus 233.71 lb-ft is 12.59 lb-ft. Run maxima change from 203.11 to 217.01 hp and 242.77 to 252.30 lb-ft: 13.90 hp and 9.53 lb-ft peak-to-peak, at different peak rpm. Both notes specify third gear, manual transmission, traction control off and a blade fan. Baseline notes specify 295/75 tires and full stock; the intake notes do not repeat tire/exhaust configuration. SAE is 1.01 for both, temperatures and humidity differ, and RPM pickup changes from inductive baseline to OBD2 intake. Hood position and test vehicle year are not identified in the chart. Current 10 hp/13 lb-ft headlines are not independent guarantees for this exact dry/later/supercharged combination.
What installation cautions and recheck apply?Carefully release smog-pump harness electrical tape without cutting wires. Use the manual illustrations to resolve its erroneous removed-fastener step cross-reference. Coupling lettering faces AWAY from the throttle body. Recheck after 100-200 miles; no numeric torque is supplied. The current exact manufacturer pages and manuals state that this product is not currently CARB exempt and is unavailable for purchase in California or use on a vehicle registered with the California DMV. A fitment statement for a supercharger does not establish emissions approval.
Verify aFe 51-76012. With the engine cool, remove the two engine-cover nuts and lift off the cover. Remove the two airbox screws, loosen throttle and snorkel clamps, disconnect MAF/harness clips, crankcase vent and small vacuum line, and remove the original housing. Disconnect the smog-pump airline and electrical plug, release its THREE C-clips from the rubber insulators and set the pump aside. Remove the original pump bracket and original inlet snorkel. Replace the original small vacuum line with the supplied 16-inch 5/32-inch line. Transfer the TWO original steel sleeves and rubber grommets to the rear housing mounts. Transfer the original MAF using supplied Torx screws and the engine-cover mounting stud using an E6 socket; fit the brass nipple. Replace the A/C bracket screw with the supplied isolation mount: HAND TIGHTEN THE RUBBER MOUNT ONLY. Fit and trim the 17-inch seal. Attach the relocation bracket to the housing with the two supplied M6 screws and fender washers. Carefully release only the electrical tape retaining the smog-pump harness; do not cut wires. Mount the housing using the illustrated original screw at the left, supplied M8 screw at the right rear and nut/washer on the isolation mount. The manual cross-reference to Step 7 for a removed mounting screw is inconsistent; identify the correct original fastener by the illustrated location. Fit the selected filter with the large T-bolt. Put the reducer small end at the throttle body with coupling lettering AWAY from the throttle, then fit its two differently sized T-bolts. Insert the tube first into the throttle coupling, then the filter, and secure connections. Transfer all THREE pump rubber insulators to the new bracket and reconnect the pump in its single aligned orientation. Route its male electrical connector UNDER the relocation bracket and airline OVER the intake tube; reconnect both. Reconnect original CCV hose, supplied small vacuum line and original MAF. Reinstall the engine cover on its transferred stud using original nuts. Fit the optional inlet plug if desired. Recheck all bolts, clamps and connectors after 100-200 miles. No numeric torque is provided.
